1467(me) vs. 1522
5.Bc4!? Better is 5.c4 establishing Maroczy Bind (look it up if you don' t know it or how to play it)
8.Bb3!? Better is 8.Bf4 In the opening develop your pieces. Do not move any piece twice unless it is absolutely necessary such as you will lose the piece or their is a clear positional reason for moving it twice in the opening.
9.Nxc6!? (exchanging your strongly centralized N at d4 is giving up control of the center). Better is
9.Be3 or Bf4 (development)
If you would like to know more please let me know.
Why did you release tension with 9. Nxc6? I think your position up to there is fine, you just need a plan. After move 9 there's no obvious weaknesses in black's position so I'd just continue developing probably with Be3 because I might want to prepare f4.
